Abstract:Objective To investigate the mosquito-trapping effect of photocatalysis mosquito lamp versus BG-trap mosquito lamp, and to provide a more effective method for the surveillance of dengue vector Aedes. Methods From August to September in 2019, one site each was selected from the four types of habitats of urban residential area, farm house, tire factory, and salvage station as the surveillance sites in Daiyue district of Tai'an in Shandong province, China, and photocatalysis mosquito lamp and BG-trap mosquito lamp were set up at the same time, with a distance of 100 m between the two types of mosquito lamps. Power supply was turned on at 15:00, and the lamps were collected at 09:00 on the next day. Surveillance was performed once in the first, middle, and last ten days of each month, and the mosquitoes were taken back to the laboratory and were frozen and sacrificed for taxonomic identification and counting. Excel 2010 and SPSS16.0 softwares were used for statistical analysis, and the χ2 test was used for the comparison of composition ratio (rate). Results The dominant mosquito species were Aedes albopictus and Culex pipiens pallens in Tai'an. A total of 212 female mosquitoes were captured by photocatalysis mosquito lamp, mainly Cx. pipiens pallens (49.53%), and a total of 1 005 female mosquitoes were captured by BG-trap mosquito lamp, mainly Ae. albopictus (55.32%). There were significant differences in the trapping rates of different mosquito species between the two types of mosquito traps (all P<0.05); the BG-trap mosquito lamp had significantly higher trapping rates of Ae. albopictus and Armigeres subalbatus than the photocatalysis mosquito lamp, while the photocatalysis mosquito lamp had significantly higher trapping rates of Cx. pipiens pallens, Cx. tritaeniorhynchus, and Anopheles sinensis than the BG-trap mosquito lamp. The highest number of mosquitoes were captured in the tire factory, with the dominant species of Ae. albopictus (65.22%), followed by the farm house, with the dominant species of Cx. pipiens pallens (47.40%). There were significant differences in the trapping rates of Cx. pipiens pallens, Ae. Albopictus, and Ar. subalbatus between different habitats (all P<0.05). For the tire factory, the mosquitoes trapped by BG-trap mosquito lamp accounted for 65.90% of all mosquitoes, mainly Ae. albopictus (89.37%); for the farm house, there were significant differences in the trapping rates of Ae. albopictus, Ar. subalbatus, and An. sinensis between the two types of mosquito traps (all P<0.05), and compared with the photocatalysis mosquito lamp, the BG-trap mosquito lamp had higher trapping rates of Ae. albopictus (17.48% vs 2.74%) and Ar. subalbatus (12.59% vs 2.74%) and a lower trapping rate of An. sinensis (20.28% vs 42.47%). Conclusion BG-trap mosquito lamp has a relatively good trapping effect on Ae. albopictus, and it is recommended to be used in the surveillance of dengue vector Aedes and the investigation of breeding sites.
